27.0.50, (void-function with-buffer-prepared-for-jit-lock)

[Andreas Röhler]

Hi,

when running an uncompiled Emacs --which is preferred for jumping into 
maybe changed sources-- got

Error during redisplay: (jit-lock-function 1245) signaled (void-function 
with-buffer-prepared-for-jit-lock)

As it turns out in jit-lock.el it's wrapped into

(eval-when-compile

Might that envelope be removed?

Thanks,
Andreas
